Currently NICD batteries still remain the most popular for power portable radios, medical equipment, professional cameras, recording devices and power tools. Since over 50% of all batteries for portable equipment - NICD. The emergence of a new electrochemical battery system although it led to a decrease of NICD batteries However, the identification of gaps new types of batteries has to renewed interest in NICD batteries. SLA batteries do not suffer from memory effect. Harmlessly allowed leave the battery in the charger device to a floating charge for a long time. Conservation charge - the best among rechargeable batteries. Taking Considering that NICD batteries samorazryazhayutsya for three months 40% of the stored energy SLA batteries samorazryazhayutsya on the same amount of one year. These batteries are inexpensive, but the cost of their operation may be higher than that of NICD, if during the lifetime require a large number discharge / charge cycles. SLA batteries commonly used in cases that require large power, weight is not critical, but cost should be low. Capacity NIMH batteries about 30% more capacity standard (not very high capacity) NICD battery of the same size. NICD elements are very high capacity provide the level of capacity close to capacity NIMH. (NICD batteries very high capacity can not provide high current load as standard NICD batteries. They also have fewer charge / discharge cycles, but more than NIMH batteries). Specific characteristics of lithium-ion batteries at least twice that performance of nickel-cadmium batteries and a well-characterized themselves when working at high currents, it is necessary, for example, using these batteries cell phones and portable computers. Lithium-ion batteries have sufficiently low self-discharge (2-5% per month). Lithium-ion batteries possess very high specific energy. Do not short circuit the battery, recharging, destruction, dismantling, piercing metal objects connection in reverse polarity, not affected high temperatures. This may cause you physical harm. In addition, should be limited maximum current charge and discharge and temperature must be monitored element. Under these precautions to formation of metallic lithium on the surface eletrodov during the operation (which is most often leads to undesirable consequences) is practically eliminated. For NICD batteries harmful presence in the charger during days. Fact, NICD batteries - this is the only type of battery, which carries its function best if periodically subjected to the full discharge. All other varieties batteries for electrochemical system prefer shallow discharge. So, for NICD batteries important periodic full level, and if it is not made, NICD batteries gradually lose their effectiveness due to the formation large crystals on the plates element, ie phenomenon called memory effect. Organization which sells batteries or which enjoys considerable their number, needs some kind of instrument capable of monitor and maintain these batteries. This tool are different analyzers. Programmable analyzer CADEX 7000 production Canadian Company CADEX ELECTRONICS INC. designed for simultaneous services in any combination 4 different batteries following electrochemical systems: sealed lead-acid (SLA), nickel-cadmium (NICD), nickel-metal hydride (NIMH) and lithium-ion (LI-ION). Analyzer serves battery voltage from 1.2 to 15 volts, a capacity of 100 mA to 24 A and maximum current charge / Discharge up to 2 A at each station. All served parameters of the battery stored in a special set of parameters, called "C-CODE". There are basic ( "BASIC C-CODE ") and advanced (" EXTENTED C-CODE ") sets of parameters. Basically set are located: the type of electrochemical system battery, rated Voltage, capacity and type of serving program. Extra set include: the value of the charging and discharge current trickle charge and the current recovery method charge and the method of determining the moment full charge, voltage end discharge and charge, as well as some others. The parameters of both sets have default and may be changed by the user. Sets of parameters are stored in replacement adapters, each of which can store up 10 such sets, or "C-CODE". Functional Features: * Ability set the capacity as a criterion for the transition to the cycle of recovery, if set value accumulator not achieved; * use in charge of the NICD and NIMH batteries short discharge pulses between pulses of charge for improve charge and reduce the "memory effect"; * Indication of the measured capacitance - A percentage of the nominal value, the presence separate indication on the principle "fit - do not fit"; Analyzer has a serial port RS-232 - to connect to the printer or computer. Inland team Print offer printing results of service and Labels batteries. Productivity analyzer is a maximum 160 batteries per month for daily maintenance 2 Parties of 4 battery 20 days month. Time Service one party from 4 to 8 hours. What importantly, complete with the analyzer separately and can be delivered software computer providing association in the network to 128 of analyzers and management of their work. So which in our daily Life can be useful given analyzer. Consider specific examples. Example 1. You purchased batch of new batteries. The question naturally arises about their condition, or rather even not the state, but the degree of conformity their parameters according to the manufacturer. Thus, it is necessary to solve typical task of the input control. Example 2. At the request of the customer must check the status of NICD or NIMH batteries and argumentative explain that to them more do: withdraw and buy new or, if you continue to exploit, what can be expected from them for further exploitation, maybe they simply could recover. Example 3. Customer said that the battery is charged, but the apparatus with a sharp increase load suddenly disconnected. For example, a cell phone it may look like this: phone no apparent reason, without filing signal of low voltage Battery life - is turned off. Or the phone is disconnected at the moment attempts to make a call. If battery contacts and phone - Clean and the connection between them dense, the reason for one - from your battery high value internal resistance. The fact is that when attempts make an outgoing call or answer an incoming phone moves from a state of low energy consumption in high increasing consumption current of 10 or more times. As a result on battery with high internal resistance is parasitic voltage drop, reduces the voltage directly on the phone to the value when triggered off his scheme. This process is instantaneous in the case of an incoming call to include a call on the phone is not even get it. And it so that you call, phone off, and you are about even not suspect. Evaluate internal battery resistance can analyzer. This procedure takes approximately 5 - 7 seconds. And this kind of rapid diagnosis battery. Example 4. Before Your task of maintaining a constant "battle" readiness certain number of batteries in case of any emergency situations, or something else like this. In this case you initially perform over batteries Program test charge and then leave the battery in the analyzer. The analyzer will constantly keep them in a state of readiness, not reload and do not spoil them as a regular charger.
